I came was getting a massage

So when they wife and I go to get waxed from our long term waxing lady. Wife goes first and then its me. When its my turn I get up on the table and the wife will take my chastity cage off so she can do my wax. When she's done our lady puts extra oil on me so the wife can put the cage back on before we leave.

After our wax we normally go and get a couple massage. We get undressed and lay on the tables with the sheets over us. Very typical thing when getting a massage. We asked for the lady that was going to massage me to be more firm as I have a bad back and need the knots in my lower back and thighs.

We're probably twenty minutes into our massage and she finally starts on my lower back and glutes. she started digging in with her elbow.  She got to my buttocks and started digging in a small circle. I am not sure if there is a pressure point there or what but that's when it happened. My Dick immediately started swelling up against my cage. It swelled so hard with no where to go. It happened! Squirt and squirt happened.  With every cum Squirt my muscles clenched on my butt! To the point she noticed my clenching.  She waited until I was done with my spasms to move. She then spoke in her native language to her partner. My wife wasn't listening as she was in her massage.

So I just came soaking the bottom sheet. I don't think anything got on the top as after that long pause and convo she kept going. So at this point I'm laying in my cum while getting a rub down massage! Finally its time to turn over.

On the turn over lucky for me since I was caged the cum leaked out and didn't stick to the top sheet. All that can be seen is the outline of the cage and lock. Since the top sheet wasn't wet so figured I was in the clear. They spoke back and forth in an Asian language.  My wife (blasaisn) does speak/understand some Asian languages.  She speaks Tokugawa and says a lot of times others know what's she's saying even though she's has to figure out what they're saying.

Anyways while turned over apparently there was a lot of conversation going on. My wife wasn't really listening as she wasn't trying to be in there conversation. Fast-forward the massage is over and time foe us to get dress and leave. Once outside I told my wife what happened. She thought it was hilarious! She told me if ever happens again to let her know and she's going to tell them in Tokugawa and see there reactions.
